To all 71/71/0111 it may concern:

Be it known that I, ANTHONY B. Fnnnimxn, a citizen of the United States, and a resident of \Yauwatosa, in the county of Milwaukee and State of \l'isconsin, have invented certain new and useful Improvements in Draft- Regulators; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invent-ion consists in certain peculiarities of construction and combination of parts hereinafter particularly set forth with reference to the accompanying drawings and subsequently claimed, one object of the invenposing one side of the blade is a crank-arm N of the slide l aforesaid. The blade is also in the path of an offset lug of thelower end of a crooked lever l, and said end of the lever is in pivotal connection with the back plate K, the other end of said lever being thickened to form a weight that is normally caught by an offset portion 1/ of a latch-plate Q, also in pivotal connection with said back plate between stop-pins r projecting from the same. A flange of the latch-plate is arranged to overhang the alarm-winding key R, pertaining to a clock S, in detachable suspension from an upper forwardly-extcnded hooktion being to provide for predetermined ani tomatic closing of a check-door and simultaneous opening of a draft-door of a heating apparatus.

A further object of the invention is to provide for holding both of said doors more or less open at the same time.

Figure 1 of the drawings is a diagram illustrating connected check and draft doors of a heating apparatus and means in accordance with my invention for controlling said doors; Fig. 2, a front elevation of the door-controlling mechanism, partly broken away and in section, on lines 2 2 in the next figure of the series; Fig. 3, a side elevation of said doorcontrolling mechanism, and Fig. -t a horizontal section on the plane indicated by line a i in Fig. 2.

Referring by letter to the drawings, A indicates a heater, and B its smoke-flue. A flexible device (I, such as a chain, is supported on suital)ly-arranged sheaves I and connects the lower draft-door D of the heater with a counterweightbracket E, attached to the check-door F of the smoke-flue. The counterweight-bracket is connected by a chain or other suitable device with a horizontal handle-arm H of a slide 1 on a vertical rod J, the ends of this red being extended through right-angle ears 0 of a back plate K, attachable to a wall or other suitable support and constituting part of a frame, said ends of the rod being fast in collars (Z, opposing the plateears. Alongitudinally-slotted front plate L of the frame is made fast to the ears of the back plate, and one edge of the slot is angularly notched to form a rack for supporting the handle-arm H of the slide I at various elevations, said arm being extended through said slot.

Loose on the rod J are offset horizontal ends of a vertical blade or rocker M, and oparm T of the back plate. The clock shown is l an ordinary alarm-clock; but the bell and clipper for the same may be omitted.

\Vhen the slide 1 is full down, the draftdoor 1) is full open and the check-door F full closed; but the reverse is true if the handlearm ll of said slide is caught in the upper notch of the front plate-rack abovespecilied, this being the position of said doors as herein shown. The lever l is normally caught by the latch-plate Q in the position herein shown, and if the clock S in suspension from the hookarm T of the back plate K be wound and set to have its alarm mechanism operate at a predetermined interval of time the reverse rotation of the winding-key b. will cause a lift of said latch-plate to free said lever. Due to automatic swing of the freed lever the blade M is swung against the crank-arm N of the slide 1 and said slide is partially rotated to bring its handle-arm ll clear of the rack, in which it is held at a greater or less elevation above the bottom of the front-plate slot, the result being an automatic full closing of the check-door F and full opening of the draftdoor I), the swing-blade M serving to prevent said handle-arm of said slide from catching again in said rack when on descent.

It is principally intended that after lire in the heater is banked for the night the draftregulator shall be set to full close the draft door I) and full open the check-door F, the clock being set and suspended, as described,

to insure automatic release of the lever P at a predetermined hour in the morning, whereby said lire may have opportunity to start up without personal attention.

The draft-regulator mechanism may be in an apartment above that in which the heating apparatus is established, and the adjustment of the draft and check doors is variable at the will of the operator independent of the clock.

2. A draft-regulator comprising a frame attachable to a suitable support and provided with an upper hook-arm and a rack edge slot, a rod in the frame, a rocker loose on the rod, a slide on said rod provided with an arm engaging the aforesaid rack-slot and another arm opposing the rocker, a rocker-actuating lever a latch for the lever, a clock for which said hook-arm constitutes a hanger, a winding-key of the suspended clock being under the flange of the latch; draft and check doors of a heatin g apparatus, and means connecting the doors with each other and said slide.

3. A draft-regulator comprising a frame attachable to a suitable support, a rod in the frame, a rocker loose on the rod, a slide adjustable on the rod to various elevations, means by which the slide is supported in adjusted position, an arm extending from said slide in opposition to the rocker, draft and check doors of a heating apparatus, means connecting the doors with each other and the aforesaid slide, a rocker-actuating lever, and a clock-controlled latch engag'eable with the lever, release of said lever serving to automatically free the slide from adjusted position.
